You have a Thinker ability that gives you the capacity to see people who have a potential to trigger in the form of a faint red mist surrounding them and you can see and hear glimpses of their trigger event and possible powers they can gain from it by looking at the mist.
You also have a Trump ability that can force those potential parahumans to experience their trigger, when you do this you and those you triggered enter a cluster, they gain a primary power and everyone gains a secondary power from the other members, those secondary powers are weaker and compliment the primary.
The more members make up the cluster the weaker the primary and the secondary will be, you cannot add more members once you make a cluster. You can unmake the cluster anytime, with everyone you triggered losing their secondary and gaining a boost to their primary, any member of the cluster can retain their secondary by draining the powers of another member.
When the cluster forms, you have the ability to select and adjust the kiss/kill dynamic between each pair of cluster members. For instance, you could set the kill dynamic to maximum strength for two members, turning them into eternal enemies. Alternatively, you could set the kiss dynamic to minimum strength for a pair, making them more inclined to cooperate.
